IMPROVEMENT IN BUTTONS.

, TO ALL WHOM IT MAY OONGERN:

Be it known that I, WILLoUcIInY II. linnn, oi' the city, county, andl State of New Yorlr, have invented an Improvement in Buttons; and I do hereby declare the following to be-a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists of a concave convey; disk, formed in respect to a projection at the back of a button, and having its edge adapted to an annular reoess or indentation in the saine, all as described hereafter, so that the cheap buttons` stamped from scraps of tnned plate may be firmly secured to articles oi' wearing apparel by riveting. I I

In order to enable others to make and use my invention, I willnow proceed to describe the manner of `carrying it into eli'ect. On reference to the accompanying drawing, which forins a part of this specification- Figure 1 .is a sectional view (drawn to an enlarged scale) of my improved button; and

Figure 2, a sectional View of a buttonY without my improvement, and illustrating the advantages of the latter. v i

' 0n reference to Iig. 2A represents a button, stamped from a disl of ordinary tinned plate, the edge ct being folded down, as illustrated, and a depression being` made in the middle, so as to form theconvexprojec tion b at the back. B is the fabric, through which` passes the rivet D, the head'of the latter bearing against the back of the said fabric, and the'stem passing through an eye in the'projection b, and the end of the stem being expanded by riveting the same within the depression. Buttons made from tinned plate are remarkably cheap,

as they can be stamped outA of scraps whichwonld otherwise be wasted. They are eiective buttons, too, if4

properly secured to the fabric; but when attached by a rivet, as illustrated in ligZ, the constant strains on the button exert such a leverage on the rivet, and the material of which the button is composed is so thin, that it soon becomes bent or worn, and sometimes torn at the eye, and loose on, and sometimes detached from, the rivet. I overcome this cliiiculty, and render thc tinned plate button available for being riveted to fabrics, by the plan illustrated in Hg. 1. In this case I use a button, A, sineilar to that described above; but instead of riveting it directly to the fabric, I interpose between the latter and the button the concave-convex disk F, which is also stamped out of tinncd plate, and the upper edge of which fits into an annular groove, e, formed at the'back of the button, where thc convex projection meets the straight portion of the same. 4'.lfhe'convexity of this projection b at the back of the button does not coincide with the concavity of the disk, but the form of the two is such that a space, e, intervenes between them, as seen in iig. 1. On the button and disk E being riveted to the-fabric,- the Vtwo become essentially a part of each other, the edge'of the disk E being so conned to the button that lateral displacement of one from the other cannot take place; hence the disk gives to the 4button a bearing surfaceagainst'the rivet extending from w to y-a bearing surface suflicient to resist all strains to which the button may be subjected, and obviating the defects above alluded to.

I claim as my invention, and desire to secure by Letters Patent,-

The concave-convex dislr E formed in respect to the projection l on the button, and having its edge adapted to an annular recess or indentation in the same, all as set forth for the purpose specified.` i

In testimony whereoil I have signed my naine to this specification in the presence of two subscribing witnesses.
